GOOSENEGK CONNECTION.

SPECIFICATION forming' part of Letters Patent N0. 787,211, dated April1], 1905.

Application filed January 12,1905. Serial No. 240.814.

To 11'71 ont if 11m/ymlm/1771,:

l-e it known that I, ALBERT W. NicuoLLs, a citizen ot' the UnitedStates, residing at New York, in the county ot' New York and State otl iNew York, have invented certain new and uset'ul improvements inGooseneck Connections; and ido declare the following to be a full,clear, and exact description ot' the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. My invention relates to improvements in gas-tube connections, andmore particularly to a gooseneck connection and a socket therefor. Theobject ot' my invention is to improve and simplify the construction andoperation of devices of this character, and thereby render the same lessexpensive to manufacture and at the same time more durable andconvenient in use.

the invention consists in certain novel features ot' construction,combination, and arrangementol" parts, as will be hereinafter more fullydescribed, and particularlyv pointed out in the appended claims.

ln the accompanying drawings, Figure 1 is a vertical sectional viewthrough a gooseneck connection and its socket constructed in accordancewith my invention. Fig. 2 isatransverse sectional view taken on the line2 2 ot' Fig. 1, and Figs. 3 and -L are views showing ditl'erentapplications of my improved connection.

Referring to the drawings by numerals, 1 5 denotes a gooseneck having atone ot' its ends a sott-rubber socket E2 and at its other end acombination cou pliug member or connection 3. The gooseneck 1 in theformot' ametal tube curved or bent, as shown, and having its endsexternally screw-thrrntded, as at si and The screw-threads 1 are engagedby similar threads lformed in one end of a connecting-tube 6, to whichis secured the soft-rubber socket 2. This connecting-tube 6 has at itsinner end an i5 annular tlange or cap T, which is engaged by one end otthe socket Q, and at the other end ot' said tube o' are annularcorrugations 8,

which serve to retain the socket 2 upon said With the above and otherobjects in view tube 6 and in engagement with its flange or cap T. Itwill be seen that the soft-rubber socket 2 is thus securely attached tothe gooseneck 1 and that there will be little or no danger ot' theseparts leaking or breaking when the gooseneck is turned or twisted, asseen in Fig. i of the drawings.

The combination coupling member or connection 3 is adapted to receiveeither of the connecting devices 9 10, which are shown in Figs. 3 and4t, the connecting devices 9 being the usual soft-rubber socket commonlyused on tubing attached to gas-stoves and the connecting' device 10being the usual internallyscrew-th read ed nipple or coupling used ontubing of gas-lamps and the like. The combination device 3 is in thevform ot' a tube inter- 65 nally and externally screw-tln'eaded, as at11 and 12, at its outer end and formed with annular corrugations 12) atits opposite end, the latter end gradually increasing in diameter, asshown. The internal screw-threads 11 are 70 adapted to engage thethreaded end 5 ot' the gooseneck 1, as shown, and the externalscrewthreads 1Q are adapted to receive the threaded nipple 10, as seenin Fig-4. The enlarged inner corrugated end 13 of the tube 3 is pro- 75vided for the purpose of receiving the softrubber socket 9, asillustrated in Fig. 2.

The construction, use, and advantages of my invention will be readilyunderstood from the foregoing description, taken in connection SO withthe accompanying drawings.

lt will be seen that the device provides a strong and durable connectionwhich will not be liable to leak and to which either of the commonlyused coupling devices may be attached.

Various changes in the form, proportion, and the minor details ot'construction may be resorted to without departing from the principle orsacrilicing any ot' the advantages ot' 90 this invention.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, iS-

1. The combination ot' a tube having exter- 95 nally-screw-threadedends,asocketconnection on one of said ends consisting of aninternallyscrew-threaded tube formed With corrugations at one of itsends and with an annular ange at its other end, a soft-rubber socketupon said connection and engaged With its ange and its corrugated end,and a combination connection upon the other threaded end consisting of atube having internal and external screwthreads at its outer end andannular corrugations upon its inner end, substantially1 as described.

2. A socket connection' comprising a tube having aneXternally-screW-threaded end, an internally-screw-threadedconnecting-tube screwed upon said end and formed at one end with anannular flange and at its other end with annular corrugatlons, and atubular socket of soft rubber upon said connecting-tube and lengagedwith its iiange and its corruga'tions.

3. The combination with a tube having an externally-screW-threaded end,of a combination connection upon said end, said connection comprising acylindrical body having internal and external screw-threads at one ofits ends and annular corrugations at its other end, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of tWosubscribing Witnesses.

ALBERT W. NICHOLLS.
